Usage: Thefilm extruder machineis mainly used in the production of low-density polyethylene(LDPE) and linear low density polyethylene(LLDPE) blends of different types of films such as liquid packaging films, composite-based film, shrinkable film, which are widely used for making packing bags, bacteria bags, fertilizer lined bags,etc. Features: It is adopting the rotary die head, the passive friction winding system, high-speed manual screen changer, digital temperature control and other advanced technologies. The extruder barrel and screw are used high-quality alloy steel through nitrogen and precision machining. With the best hardness and corrosion resistance. Back-to-back two station double winder, adopting torque motor and can maintain proper tension winding and tidy, convenience for roll changing.
